There were numerous user group meetings as Salesforce Partners took advantage of their customers attendance at Dreamforce to host these meetings. I saw events scheduled by Zuora (here) Cloud9, Work Day and Marketo.
Turnouts were good despite the hurricane which delayed some east coast attendees. None the less, the Zuora event was vastly oversubscribed — more than five hundred people attended though as of the Friday before, about three hundred had registered — a lot more than the hoped for 250.
In these videos, I lead a panel discussion with
>>Darren Cunningham, VP Marketing, Informatica Cloud
>>Heidi Hollenbeck, VP Billing, Open Range
>>Anne Driscoll, VP Marketing and Business operations, Ning
Users from Dell, AAA, Salesforce.com discuss their use of Zuora.
